Induction Lights

The internal electrodeless lamp or induction light is a gas discharge lamp in which the power required to generate light is transferred from outside the lamp envelope to the gas inside via an electric or magnetic field, in contrast with a typical gas discharge lamp that uses internal electrodes connected to the power supply by conductors that pass through the lamp envelope. There are three advantages to elimination of the internal electrodes:

    Extended lamp life, because the internal electrodes are usually the limiting factor in lamp life.
    The ability to use light-generating substances of higher efficiency that would react with internal metal electrodes in normal lamps.
